The CD74HC541E is an inverting octal Buffer/Line Driver with 3-state outputs and the capability to drive 15 LSTTL loads. The output enables (OE1\\) and (OE2\\) control the 3-state outputs. If either OE1\ or OE2\ is HIGH the outputs will be in the high impedance state. For data output OE1\ and OE2\ both must be LOW.
Buffered inputs
Bus line driving capability
Balanced propagation delay and transition times
Significant power reduction compared to LSTTL logic ICs
High noise immunity - NIL = 30%, NIH = 30% of VCC at VCC = 5V
Typical propagation delay = 9ns at VCC = 5V, CL = 15pF, TA = 25°C
